    摘要： A well screen system for use in a wellbore has an elongate base pipe and a screen encircling the base pipe. The screen is configured to filter against passage of particulate into a center bore of the base pipe. The base pipe has a fluid impermeable portion exterior to the screen. A cover sleeve resides over the fluid impermeable portion of the base pipe. A drain tube with a fluid permeable sidewall resides exterior to the base pipe and screen, affixed to the cover sleeve. The drain tube is adapted to communicate fluid from the wellbore around the fluid impermeable portion to the screen.

    摘要： A system for coupling a shunt tube of a first screen assembly to a shunt tube of a second screen assembly includes an elongate jumper tube and a misalignment joint. The misalignment joint has a first end coupled to the jumper tube. The first end is moveable relative to a second end of the misalignment joint.

    摘要： A downhole tool for use in a wellbore tubular string comprises a housing having a bore therethrough forming part of a fluid flowpath through the wellbore tubular string, a sliding member operable to slide with respect to the housing, a plurality of magnetic pins, and a corresponding plurality of springs. A sliding line is formed by interfacing surfaces of the sliding member and the housing, and the plurality of pins comprise a locked position and an unlocked position whereby in the locked position at least one pin spans the sliding line to prevent the sliding member from sliding with respect to the housing and in the unlocked position no pins span the sliding line. The plurality of springs biases the pins towards the locked position.

    摘要： Casing expansion and formation compression for permeability plane orientation. A method of forming at least one increased permeability plane in a subterranean formation includes the steps of: installing a casing section in a wellbore intersecting the formation; expanding the casing section in the wellbore; and then injecting a fluid into the formation, the injecting step being performed after the expanding step is completed. Another method includes the steps of: applying an increased compressive stress to the formation, the compressive stress being radially directed relative to a wellbore intersecting the formation; and then piercing the formation radially outward from the wellbore, thereby initiating the increased permeability plane. Yet another method includes the steps of: applying a reduced stress to the formation, the reduced stress being directed orthogonal to a wellbore intersecting the formation; and then piercing the formation with at least one penetration extending radially outward from the wellbore, thereby relieving the reduced stress at the penetration.
